Abstract:
Objective To establish a large biological sample bank from a great number of participants for genetic cohort study.An accurate quick identification must be ensured for each biological sample in the operation, which helped to make it viable for the long term follow-up in the biobank.
Methods The bar code-identifying technology was applied in the conduct of all procedures including sample collection, handling, storage and retrieval.
Results A new operating pattern using automatic bar-coding as the principal technology was developed.The biological sample bank including 10 thousand individuals was established.The implementation of the bar code-identifying information system in the huge biobank reduced the handling time for every sample and work efficiency was increased 1.5 times.
Conclusion Using bar code technology can efficiently avoid errors in distinguishing samples.The developed operating pattern worked accurately, dependably and efficiently in our laboratory.It helps us to achieve computerization completely in medical research and improve the quality of genetic cohort study.
